I've always been of the opinion that the best defense is a good offense, and if you're dragged into court and have the slightest justification, you should file a countersuit.
EVS was sitting on this trademark stuff and possibly was going to let it slide, but now that this stupid asshole has dragged him into court, he has no reason not to unload with both barrels.
I think the funniest outcome would be if Peggy gets scurred and drops his own suit (or it just gets thrown out) and EVS says fuck you and continues to pursue his own.
